MCULINK PRO DEBUG PROBLEM

emfact — Mon, 02 Jan 2023 03:29:48 GMT

I am using LPC5506 with SDK example,

I am able to flash it using Flash tool in MCUEXPRESSO and output is also ok.

But unable to DEBUG it. I am getting following error.

Target error from Commit Flash write: Ep(04). Cannot halt processor.

ERROR SCREENSHOT ATTACHED.

Please help me out.

Thank you

I have some questions about the TJA1145T/FD, hope you can help. Should PNC and WUF be used together? If we want to use WUF https://testmyspeed.onl/ function, should we also use PNC?

Hello @emfact,

Could you please try the following suggestions? 1. Please double check that you stop previous debugging session instance before trying to run a new one. 2. Delete the .launch of the project and try to debug again. 3. Try out another example like a Hello World to see if the problem continues.

If the problem persists, could you please share your project?

Best regards, Raul.

I had tried all 3 options you have mentioned but no luck.

Following GDB protocol problem is seen in console .

Hello @emfact,

Could you please tell us what board are you using? Is it a custom board or is it a NXP development board?

At the meantime, could you please try performing a mass erase to the flash memory using the GUI Flash Tool before debugging?

Finally, could you try updating the firmware of the MCU-Link Pro? For this, please refer to the following links: Getting Started with the MCU-Link Pro and MCU-Link Pro User Manual.

Best regards, Raul.

Attached my settings.

Thanks for your support
